Hi pot testing manual

The test method is simple: apply a very high voltage potential (thus the name “hi-pot”) between the “hot” (L1, L2, etc.) “neutral” (L0) wires and the main safety ground point and monitor the system for excessive current www.doorway.ru Size: KB. manually press the Function switch or Hipot button to conduct a Hipot test. Having manual control of the Hipot test should give the operator ample time to remove their hands from any cable connections and prevent the possibility of.

Both AC and DC hipot tests are possible and, in general, the test should use the same type of voltage as it would be during normal operation. However, if a DC hipot test is used on an AC circuit, the hipot voltage should be two times the peak (2 x x RMS) + V. Desirable dielectric withstand test features. Adjustable maximum output voltage.

If the instrument has an external safety-ground connection be sure that this is connected. DC Hipot testing. Megger is the originator of the insulation tester with over years of experience and leadership in providing high performance insulation testers for electrical equipment diagnostic applications. Regular insulation testing is one of the most cost effective methods of identifying aging in any type of electrical equipment.
